Abstract: Abstract: At present, the wine grape harvest in Xinjiang totally depends on labor, which seriously restricts the development of the wine grape industry, and therefore, its harvesting mechanization has become an inexorable tendency. In addition, the wine grapevines in Xinjiang need to be buried to resist the cold in winter, its tree style is multiple-trunk fan-shaped while the style of foreign wine grape tree is trunk-shaped primarily, and there are large differences in fruit distribution and vibration transmission attenuation between them. Thus, the foreign wine grape harvesting machine can't be directly applied to the harvest of wine grape in Xinjiang. To solve these problems, a self-propelled grape harvester was designed and manufactured. The harvester operates with one line at a time, and can complete many jobs such as separation, conveying, cleaning and collection of wine grape at one time. It is mainly composed of shaking separation mechanism, collecting and conveying mechanism and self-propelled hydraulic chassis, and all parts of the harvester are powered hydraulically. In order to get better harvesting effect, the way driving the end of the rib components in the shaking separation mechanism is used to achieve one kind of shaking effect with large amplitude and little disorder, which can overcome the issue that wine grapevines in Xinjiang have the fast vibration energy attenuation and low transfer efficiency. Combining the kinematic and dynamic analysis for the shaking separation mechanism's key components and preliminary experimental study of the shaking separation test apparatus on the wine grape harvesting, the optimal working combination parameters of the shaking separation were determined. When the collecting and conveying mechanism works, 2 rows of symmetrical guide-supported double hinge chains are driven to do rotary motion and take both sides of the hoppers to collect and convey the grape fruits to the bins. The hoppers on the double hinge chains are made of flexible material and tightly meshed with each other in order to avoid damage to the vines and fruit leakage respectively. The main structural parameters of the collecting and conveying mechanism were determined as follows: the length and width of the hopper bottom area were 1 200 and 800 mm respectively, and each receiving hopper's volume was 0.08 m3. The main function of the self-propelled hydraulic chassis is providing power for the harvester and adjusting the harvester's operating parameters. The driving four wheels and steering front-wheel are used in the self-propelled hydraulic chassis, and its four wheels utilize the folding lift mechanism; in this way, the harvester's flexibility and adaptability in the field are improved. Finally, the harvester's field performance was tested. The test results showed that when the terrain was flat and the grape sugar content reached 18%, the harvester achieved the best harvesting effect at the 2 km/h working speed. At this speed, the average productivity was 0.6 hm2/h, the fruit average recovery rate reached 93.8% and the fruit average broken rate was less than 9.3%. The average productivity and fruit average recovery rate of this harvester have approached the level of foreign wine grape harvester basically, but the fruit average broken rate is relatively high. This is because the fruit distribution of Xinjiang wine grape is scattered, which increases the odds that the vibration ribs touch the grapes. However, the harvester gives the relatively poor harvest stability and reliability, and displays the high impurity rate; and this test also finds that some viticulture agronomy is not conducive to the mechanized harvesting for wine grape. The later work is mainly to improve and optimize the whole harvester structure to enhance the harvester's performance and harvest quality. This research provides a reference for promoting the localization process of wine grape harvest machine in China.
